Hey everyone. Second post here, sort of a follow up I guess from my last post. I mentioned there that I acquired two new babies and since maybe last week, one of themy has had an odd quack. Her chirp is fine but is followed up by an odd noise. She is a 2.5 week old pekin. https://drive.google.com/file/d/0B0jNbNj-tae8OEtRcW4yd0I2VWs/view?usp=drivesdk Here's a small audio clip of it I recorded. I hope she doesn't have a respiratory infection. I change their bedding constantly and they are in a room that is kept at 75 degrees at all times. Any advice is appriciated. Thanks!
